Electromagnetism

What happens to magnetic field strength of solenoid if resistance increases?. It will decrease. It will increase. Nothing happens. Information not sufficient.

If I choose thicker wire will magnetic field strength of solenoid be stronger?. Maybe. No. Yes.

Can direct current be used in transformers?. No. Yes. Depends on how big the transformer is.

If a magnet is dropped through a conducting circular wire, the acceleration of falling object.... has value greater than acceleration due to gravity. has value lesser than acceleration due to gravity. has value equal to acceleration due to gravity.

Magnetic levitation is used in. bus. train. cars. shoes.
