Question

True or False please

1. When it is connected in a circuit, an inductor must resist having current flow through it

2. An insulated metal coil is wrapped around the outside of an ideal solenoid. If the current in this solenoid is decreasing, a current is induced in the coil due to an electric field caused by the changing magnetic field in the solenoid

3. Two protons have velocities parallel to each other and with same magnitude. In the laboratory reference frame, each one experiences an electric and a magnetic field due to the other charged particle; but in the frame of each proton they experience only an electric field

Answer 1

1. true yes, When it is connected in a circuit, an inductor must resist having current flow through it

it creates a negative potential to do so.

2. An insulated metal coil is wrapped around the outside of an ideal solenoid. If the current in this solenoid is decreasing, a current is induced in the coil due to an electric field caused by the changing magnetic field in the solenoid.This is true

this is also called electro magnetic induction

3. Two protons have velocities parallel to each other and with same magnitude. In the laboratory reference frame, each one experiences an electric and a magnetic field due to the other charged particle; but in the frame of each proton they experience only an electric field

This is also true

I hope its fine

stay safe
