FLASHCARD QUESTION

Front

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

Back

The force on a charged particle moving in a magnetic field is perpendicular to both the velocity of the particle and the magnetic field direction, determined by the right-hand rule.

FLASHCARD QUESTION

Front

What is the right-hand rule in magnetism?

Back

The right-hand rule states that if you point your thumb in the direction of the current (or velocity of a positive charge) and your fingers in the direction of the magnetic field, your palm will point in the direction of the magnetic force.

FLASHCARD QUESTION

Front

What are magnetic poles?

Back

Magnetic poles are the regions of a magnet where the magnetic force is strongest. Every magnet has a north pole and a south pole.

FLASHCARD QUESTION

Front

What is the principle of electromagnetic induction?

Back

Electromagnetic induction is the process by which a changing magnetic field induces an electromotive force (EMF) in a conductor.

What is a magnetic domain?

Back

A magnetic domain is a region within a magnetic material where the magnetic moments of atoms are aligned in the same direction.
