When a current carrying wire is held parallel to and above a compass n

1.	When a current carrying wire is held parallel to and above a compass needle and the current flows from North to South, which direction the N-Pole of the compass needle will get deflected?
Answer» EXPLANATION: . Why does a compass needle get deflected when brought near a BAR magnet? ANS. A compass needle is a small bar magnet with north and south pole. The compass needle deflects due to repulsion/attraction with the bar magnet. 2. Draw magnetic field lines around a bar magnet. Ans. 3. List the properties of magnetic lines of force. Ans. Properties of magnetic field lines of force: (i) Magnetic field lines travel from N-pole of magnet TOWARDS 5-pole, outside the magnet and from S-pole to N-pole inside the magnet. (ii) The strength of magnet/magnetic field is given by how close the field lines are if the field lines are CLOSER magnet is stronger. (iii) No two magnetic field lines ever intersect each other.

ANS. A compass needle is a small bar magnet with north and south pole. The compass needle deflects due to repulsion/attraction with the bar magnet.

2. Draw magnetic field lines around a bar magnet.

Ans.

3. List the properties of magnetic lines of force.

Ans. Properties of magnetic field lines of force:

(i) Magnetic field lines travel from N-pole of magnet TOWARDS 5-pole, outside the magnet and from S-pole to N-pole inside the magnet.

(ii) The strength of magnet/magnetic field is given by how close the field lines are if the field lines are CLOSER magnet is stronger.

(iii) No two magnetic field lines ever intersect each other.
