How can a solenoid be used to magnetise a steel bar?
Answers
Answer:
A steel bar to be magnetised is placed in a solenoid (wire coil) as shown. ... The current flowing through the solenoid produces a magnetic field that will magnetise the steel bar. The resistance of the rheostat can be reduced to increase the current flowing in the circuit hence increasing the strength of the magnet.
