How does the strength of the magnetic field depend on the current?​

Sagot :

Answer:

The strength of magnetic field is directly proportional to the current flowing in the conductor. If current is increased , then the magnetic field strength is increased . If current is decreased , then the strength decreases . If distance is increased , then the magnetic field strength is increased,

1) if the radius increases the magnetic field lines go farther and farther so the strength of the magnet decrease.

2) if the number of turns increase then the magnetic field lines become denser. So the strength of the magnet increase.

3) if the flowing in the circuit increases then the number of the magnetic field lines increased so strength of the magnet increase
