True / False 1. Current - carrying coil, when suspended freely, can rest in any direction.
2. Silver is an insulator of electricity.
3. All metals are conductors of electricity.
4. An electric bell uses an electromagnet.
5. electromagnet with the soft iron core is a temporary magnet.
6. use cells as the source of electricity to run an electric immersion rod.
7. For a circuit to be complete, every part of it must be made up of conductors.
I WILL MARK THIS AS BRAINLEST!!!

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
