Flashcard on Magnetism

Front

What is the formula for calculating the magnetic force on a current-carrying wire?

Back

F = BIL, where F is the magnetic force, B is the magnetic field strength, I is the current, and L is the length of the wire.

Front

If both the current and magnetic field are doubled, how does the magnetic force change?

Back

The magnetic force quadruples.

Front

True or False: The strongest part of a magnet is the middle part.

Back

False. The strongest parts of a magnet are the poles.

Front

What is a common example of a magnetic material?

Back

A paper clip is an example of a magnetic material.

Front

What are the regions within a material where the magnetic fields of atoms are aligned called?

Back

Magnetic domains.

Front

Which of the following is NOT a naturally magnetic material: iron, copper, nickel, or cobalt?

Back

Copper is NOT naturally magnetic.

Front

What is the term for the area around a magnet where magnetic forces can be detected?

Back

Magnetic field.

Front

What happens to the magnetic force if the length of the wire in a magnetic field is increased while keeping current and magnetic field constant?

Back

The magnetic force increases.

Front

What is the direction of the magnetic force on a current-carrying wire in a magnetic field?

Back

The magnetic force is perpendicular to both the direction of the current and the magnetic field.

Front

What is the unit of magnetic field strength?

Back

Tesla (T).
