Answer 1

Answer:

Mark brallint

Explanation:

Solenoids are most commonly used as electromagnets, and all the examples so far are that kind of solenoid. But there are some other uses. They can be used to slow the flow of electricity in a circuit, making them an example of an inductor, or an impedance device.

Answer 2

Explanation:

A solenoid is a conducting wire wound around an insulating material. A current carrying solenoid induces a magnetic field around it.A solenoid has a large number of close, insulated circular turns. The magnet at the centre of current carrying circular wire is along the axis; so when current is passed in a solenoid, the magnetic fields due to all circular turns are added and hence the field line becomes just as for a bar magnet. Solenoids are most commonly used as electromagnets
