5 factors affecting solenoid strength
5 factors affecting solenoid strength
Current, length, area, turns, iron core
Current size effect on solenoid
Current size effect on solenoid
Greater current = stronger field
Number of turns effect on solenoid
Number of turns effect on solenoid
More turns = stronger field
