What conditions must be present for a charge to experience a magnetic force?5 min read

Reading Time: 4 minutes

1. The charge must be moving. 2. The velocity of the charge must have a component that is perpendicular to the direction of the magnetic field.

What are the conditions under which a charged particle experiences magnetic force in a magnetic field?

When moving through a magnetic field, the charged particle experiences a force. This force is given by the charge times the vector product of velocity and magnetic field.

Why does a charge experience force in magnetic field?

A moving electric charge behaves like a mini-magnet as it creates its own magnetic field. This means it experiences a force if it moves through an external magnetic field (in the same way that a mass experiences a force in a gravitational field or a charge experiences a force in an electric field.)

What are the 2 criteria necessary for a substance to be considered a magnet?

A magnet is a material with poles and a magnetic field created by the configuration of its electrons. It must contain one of the three naturally magnetic metals, iron, nickel, and cobalt.

Under what conditions does a moving charge experience minimum force?

(ii) Minimum force: When this charge is moving in the direction of the magnetic field.

What conditions affect magnet charges?

When charges are stationary, their electric fields do not affect magnets. But, when charges move, they produce magnetic fields that exert forces on other magnets. When there is relative motion, a connection between electric and magnetic fields emerges—each affects the other.

What are the 4 characteristics of magnetic force?

General Properties of Magnetic Lines of Force They never cross one another. They all have the same strength. Their density decreases (they spread out) when they move from an area of higher permeability to an area of lower permeability. Their density decreases with increasing distance from the poles.

When can an electric charge experience a force?

When charge is moving in the direction perpendicular to the magnetic field then it will experience the magnetic force. Was this answer helpful?

How does magnetic force occur?

The magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by the motion of charges. Two objects containing charge with the same direction of motion have a magnetic attraction force between them.

What is the magnetic force acting on the charge?

Lorentz force, the force exerted on a charged particle q moving with velocity v through an electric field E and magnetic field B. The entire electromagnetic force F on the charged particle is called the Lorentz force (after the Dutch physicist Hendrik A. Lorentz) and is given by F = qE + qv × B.

What are the 3 factors that determine magnetic properties?

Alignment of electrons, atoms and domains are important in determining the magnetic response of a material and whether it is a magnet.

What are the requirements for a situation to produce a magnetic field?

Magnetic fields occur whenever charge is in motion. As more charge is put in more motion, the strength of a magnetic field increases. Magnetism and magnetic fields are one aspect of the electromagnetic force, one of the four fundamental forces of nature.

What are the 3 rules of magnets?

Some would claim that there is only one right-hand rule, but I have found the convention of three separate rules for the most common situations to be very convenient. These are for (1) long, straight wires, (2) free moving charges in magnetic fields, and (3) the solenoid rule – which are loops of current.

Under what conditions is the force experienced?

Factors that affect force experienced are : Angle between magnetic field and current (Maximum when perpendicular) Strength of Magnetic field strength (Stronger magnetic field → Stronger force) Amount of current in conductor (Higher current → Stronger force)

What are the factors at which the force experienced by a charged body depends upon?

Solution : Force depends on (i) current flowing in the conductor, (ii) length of the conductor and (iii) strength of magnetic field.

What is the force experienced by a moving charge in magnetic field?

Detailed Solution. CONCEPT: Lorentz force: A charged particle moving relative to a magnetic field experiences a force due to the magnetic field. This force is called the Lorentz force.

Under what conditions will the force exerted by the magnetic field on a charged particle be i maximum and II minimum?

The force will have a magnitude F=qvB sin q, thus it will be maximum if sin q is maximum. Thus angle between velocity and magnetic field should be 90 or the charge particle moves perpendicular to the velocity vector.

Under which condition the force exerted by a magnetic field on a moving charge particle become zero?

Under what condition is the force acting on a charge moving through a uniform magnetic field minimum? Solution : When a charge is moving in the same/opposite direction (i.e. parallel or antiparallel) of the magnetic field, the foce acting on the charge is zero (minimum or no force).

Under what condition is the force experienced in a magnetic field maximum?

When the direction of the electric current and the external magnetic field are perpendicular to each other, the strength of the force on the conductor is maximum or largest.

Under which of the following conditions will an electric charge experience the largest magnetic force?

Thus the charge traveling perpendicular to the magnetic field experiences the maximum force.

What two factors affect magnetic force?

The factors affecting the strength of a magnetic field at a point due to a straight current-carrying conductor are the magnitude of the electric current and the perpendicular distance between the point and the conductor.

What are the 3 things that cause a magnet to lose its magnetic property?

However, when it cools the full magnetism is restored. Thus, a magnet can lose its properties if it is heated, hammered or if it is dropped from a height.
