The Motor Effect Flashcards

All 4 cards in this deck

What is the motor effect?

A current-carrying conductor placed in a magnetic field (near a magnet) experiences a force.

What causes the force on a current-carrying wire placed near a magnet?

The interaction between the magnetic field produced by the current and the magnetic field of the magnet.

How does the force on the magnet compare with the force on the current-carrying wire when their fields interact?

The forces are equal in size and opposite in direction.

True or false? The force on a current-carrying wire is greatest when the wire is parallel to the magnetic field.

False. The force is greatest when the wire is at right angles to the field, and zero when it is parallel to the field.
