How does a solenoid behave like a magnet A solenoid behaves like a magnet whilst an electric current passes via its coils. This current generates a magnetic discipline across the solenoid, just like how a bar magnet produces a magnetic discipline. The magnetic area inner a solenoid is powerful and uniform, and the solenoid has north and south poles, just like a everyday magnet. When the contemporary flows, the solenoid creates a magnetic discipline which can appeal to or repel different magnetic substances, making it function successfully as a magnet. The power of this magnetic field depends on factors just like the range of coils inside the solenoid and the quantity of cutting-edge flowing through it.
