Magnetic Effect of Electric Current
Bar magnet vs Electromagnet
Compare the figures
Electric current produces magnetic field
Arrangement is a circuit above a pivoted magnetic needle in such a way that the part AB of the conductor is parallel and close to the magnetic needle
Right Hand Screw Rule
It is similar to Right Hand Thumb Rule
Solenoid
Study the figures
A solenoid is an insulated wire wound in the shape of a helix.
Solenoid and Bar magnet
Solenoid is identical with Bar magnet. Analyse and compare the ability of solenoid and bar magnet to bring changes in permanency of the magnetism, polarity and the strength of the magnetism.
