What is magnetic compass ?

Suggest an activity to prepare a magnetic compass by using an iron needle and a bar magnet

Which is more powerful between a magnetic compass needle and a bar magnet ?

A magnet compass is placed at the point 'X' , the mid point of the line segment joining AB along the axis of the coil of the electromagnetis in a horizontal plane . What would be the direction of the magnetic compass ? Explain.

How does a magnetic compass behave at a neutral point?

Arrange the following steps in sequential order to demonstrate the magnetic effect of the elctric cur-rent using magnetic compass. (A) Wind an insulated conducting wire around the magnetic compass such that the axis of the coil is directed along east west direction and con-nect the free ends of the wire to a cell through a switch. (B) Take a magnetic compass. (C ) When current flows through the conducting wire, it behaves as a magnet and deflects the compass needle. (D) When the switch is closed, the magnetic nee-dle in the compass deflects from its initial posi-tion and when the switch is opend, the needle comes back to its initial position.
