Magnetism and the Right Hand Rule

Front

What is magnetism?

Back

Magnetism is a physical phenomenon produced by the motion of electric charge, which results in attractive and repulsive forces between objects.

Front

What is the Right Hand Rule?

Back

The Right Hand Rule is a mnemonic used to determine the direction of the magnetic force on a charged particle moving in a magnetic field. Point your thumb in the direction of the velocity (v), your fingers in the direction of the magnetic field (B), and your palm will point in the direction of the force (F) on a positive charge.

What happens to a negatively charged particle in a magnetic field?

Back

A negatively charged particle will experience a force in the opposite direction to that predicted by the Right Hand Rule.

Front

What is the formula for the magnetic force on a charged particle?

Back

F = q(v × B), where F is the magnetic force, q is the charge, v is the velocity of the particle, and B is the magnetic field.

Front

What is the direction of the magnetic force on a charged particle moving perpendicular to a magnetic field?

Back

The magnetic force is always perpendicular to both the velocity of the particle and the direction of the magnetic field.

Front

What is the effect of a magnetic field on a charged particle moving parallel to the field?

Back

If a charged particle moves parallel to the magnetic field, it experiences no magnetic force and continues in a straight line.

Front

How does the charge of a particle affect its motion in a magnetic field?

Back

The direction of the magnetic force depends on the sign of the charge: positive charges follow the Right Hand Rule, while negative charges move in the opposite direction.

Front

What is the significance of the magnetic field lines?

Back

Magnetic field lines represent the direction and strength of the magnetic field; they emerge from the north pole and enter the south pole.

Front

What is the relationship between velocity, magnetic field, and force?

Back

The magnetic force is maximized when the velocity of the charged particle is perpendicular to the magnetic field.

Front

What is the effect of increasing the strength of the magnetic field on the force experienced by a charged particle?

Back

Increasing the strength of the magnetic field increases the magnetic force experienced by the charged particle.
