Field Forces Test Retake

Front

What is the principle behind generating electric current using a magnet and a wire?

Back

Moving a magnet next to a wire induces an electric current in the wire due to electromagnetic induction.

Front

How does the distance between two objects affect the gravitational pull between them?

Back

As the distance between two objects increases, the gravitational pull between them decreases.

Front

What is Coulomb's Law used for?

Back

Coulomb's Law calculates the electrostatic force between two charged objects based on their charges and the distance between them.

Front

What is the formula for Coulomb's Law?

Back

Front

What is the weakest fundamental force in nature?

Back

Gravity is considered the weakest fundamental force.

Front

What is electromagnetic induction?

Back

Electromagnetic induction is the process of generating electric current in a conductor by changing the magnetic field around it.

Front

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.

Front

What happens to the electrostatic force if the charges are doubled?

Back

If the charges are doubled, the electrostatic force increases by a factor of four, according to Coulomb's Law.

Front

What is the relationship between electric current and magnetic fields?

Back

An electric current generates a magnetic field around the conductor, and a changing magnetic field can induce an electric current.

Front

What is the significance of the right-hand rule in electromagnetism?

Back

The right-hand rule helps determine the direction of the magnetic field relative to the direction of the current.
