Question

How does solenoid magnetize a substance?​

Answer 1

Explanation:

A solenoid is a long coil of wire wrapped in many turns. When a current passes through it, it creates a nearly uniform magnetic field inside. ... The energy density of the magnetic field depends on the strength of the field, squared, and also upon the magnetic permeability of the material it fills

Answer 2

Explanation:

A solenoid is a long coil of wire wrapped in many turns. When a current passes through it, it creates a nearly uniform magnetic field inside. ... The energy density of the magnetic field depends on the strength of the field, squared, and also upon the magnetic permeability of the material it fills.

You can create a stronger, more concentrated magnetic field by taking wire and forming it into a coil called a solenoid. You can create a stronger magnetic field by taking wire and forming it into a coil; the field is more concentrated in the center of the loop than outside the loop
