Question

1.) Which of the magnetic fields produced resembles that of a magnet bar?

2) If the intensity of the electric current is increased, does the magnetic field intensity increase or decrease?

3) If the number of turns or turns is increased in a coil, does the magnetic field increase or decrease? They have up

Answer 1

Solution :

1. The magnetic field produced by a solenoid has same pattern as a bar magnet. It shows some ot the properties which are same as bar magent.

2. In a current carrying conductor the magnetic field produced is directly proportional to the electric current flowing. If you increase the current the magnetic field would also increase.

3. Yes the field also depend on the number of turns per unit length if you are increasing the number of turns the magnetic field would increase.
