Question

A loop of wire is placed into a magnetic field between two magnets. Since this is a three dimensional, a dashed line is drawn through the loop to show the imaginary slice we take that allows us to picture the electron current flow from different perspectives. How do you think the loop will move? Describe this from the front view perspective


a) clockwise
b) counter-clockwise
c) up
d) down

​

Answer 1

Answer: the loop will move up

Explanation:

Whenever an electric current cuts across magnetic field lines, a force is exerted on the current - carrying conductor

According to Fleming's left hand rule, the thumb is the direction of motion.

First finger is the direction of magnetic field, while the second finger is the direction of the conventional current.

When a current flow in the will, the wire will experience an upward force. And continue to rotate in an up - down direction. Therefore, the loop will move up.
