Solve this:
Q. Explain the formation of micelle when soap is dissolved in hydrocarbons.
Q.16. A coil is connected to a galvanometer. When the N-pole of a magnet is pushed into the coil, the galvanometer is deflected to the right. What deflection, if any, is observed when :
(a) the N-pole is removed ?
(b) the S-pole is inserted ?
(c) the magnet is at rest in the coil ?
State three ways of increasing the deflection on the galvanometer.

Do we have to write about electromagnet or the electric current produces a magnetic field?
Question No. 27
Radha wraps insulated copper wires onto an iron nail. To the ends of the wire, she connects a cell and a switch. When she switches-off the switch, she observes that the pins cling to the nail. Explain the reason for her observation.
Solution
When Radha closes the switch, electric current flows through the wire. It behaves as a magnet because of the magnetic effect of current. Hence, the pins cling to the nail.
