Use Lenz's law to explore what happens when an electromagnet is activated a short distance from a wire loop. Note, an electromagnet is a solenoid with a magnetic material inside its core. In this case, the magnetic material is iron, whose magnetic polarization amplifies the external magnetic field produced by the solenoid. You will need to use the right-hand rule to find the direction of the induced current.

By Lenz's law, for, coils, if he North pole is activated on the electromagnet, the pole on the side of the coil closest to the electromagnet will be a North pole and the flow of the current will be counter clockwise

Explanation:

Lenz's law states that where a changing magnetic field induces an electric current in a solenoid, the magnetic field that is produced by the coil opposes the initial activation of the electromagnet in the solenoid

By Flamings right hand rule, we have;

Therefore, by Lenz's law, for, coils, if he North pole is activated on the electromagnet, the pole on the side of the coil closest to the electromagnet will be a North pole and the flow of the current will be counter clockwise.

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary

the answer is 3.1 his answer is wrong mines is right
