Question: If the current in a coil is reversed, what happens to the direction of the magnetic field produced by the coil?

Options:

Correct Answer: It reverses

Solution:

Reversing the current in a coil reverses the direction of the magnetic field produced.

If the current in a coil is reversed, what happens to the direction of the magnetic field produced by the coil?

If the current in a coil is reversed, what happens to the direction of the magnetic field produced by the coil?

Step 1: Understand that a coil of wire produces a magnetic field when an electric current flows through it.
Step 2: Recognize that the direction of the magnetic field is determined by the direction of the current in the coil.
Step 3: When the current in the coil is reversed, it means the flow of electricity changes direction.
Step 4: Since the direction of the magnetic field depends on the direction of the current, reversing the current will also reverse the direction of the magnetic field.
Step 5: Conclude that if the current is reversed, the magnetic field produced by the coil will also point in the opposite direction.

Electromagnetism – The relationship between electric current and magnetic fields, specifically how reversing current changes the magnetic field direction.
