A coil of wire carrying a current is a solenoid.?

Question

true or false?

Answer 1

This is a tricky question because a solenoid doesn't have to be connected to a power source but it remains a solenoid even though it's not carrying a current.

Generally, I wouldn't call it a solenoid unless the coil is intended to pull in a metal object.

But the basic description is correct.

Answer 2

false a solenoid is a high amperage switch with two separate circuits that allows current flow across the switch when another current flows through the coil causing a magnetic flux to move a metal cylinder that turns on the switch for the higher amperage circuit so that current can flow

Answer 3

false, i agree with michal, and i think marc is thinking of a relay

Answer 4

false.....

a solenoid is the mechanical device that is actuated when the coil creates a magnetic flux/field, when current is applied to the coil.

Answer 5

I thought it was an electromagnet.
