D.3 - 2 - The Curl Right Hand Rule

What is the primary purpose of the Curl Right Hand Rule?

• To determine the direction of electric current in a circuit.

• To find the direction of the magnetic field induced by a moving electric current.

• To calculate the magnitude of an electric current.

• To identify the type of material used in a wire.

Which statement accurately describes the relationship between electric current and magnetic fields?

• Only magnetic fields can induce electric currents.

• Only electric currents can induce magnetic fields.

• Electric currents induce magnetic fields, and magnetic fields can also induce electric currents.

• Electric currents and magnetic fields are unrelated phenomena.

If an electric current flows upwards through a straight wire, what is the direction of the induced magnetic field to the right of the wire?

• Out of the page

• Into the page

• Upwards, parallel to the current

• Downwards, opposite to the current

When an electric current moves in a counter-clockwise circle, what is the direction of the induced magnetic field inside the circle?

• Into the page

• To the right

• Out of the page

• To the left
