In the electrical method of magnetisation, the end in which current flows in clockwise direction becomes

Which of the following is not an artificial magnet?

Usually the North Pole of a magnetic needle is painted ______

Magnetic field induction of a uniform field is 0.385×10^–4 T and pole strength is 2Am Then find the force acting on magnet in C.G.S system?

To prevent demagnetisation the bar magnets are arranged in pairs with... poles facing each other

Magnetic keepers are used for ............... magnets

Lines of force runs from ___ to ___ inside the magnets

A magnet has pole strength 3Am and moment 24 Am2 Then find its length?

The smallest value of x² – 3x + 3 in the interval is

The alternate way to solve the question is to put both the values of interval of the function. Then we compare the values. We also check if the first derivative is postive or negative. If it's negative, the given function is decreasing. And if postive, the given function is increasing.

Net magnetic field at the centre of the circle O due to a current carrying loop as shown in figure is

Deflection of galvanometer in the circuit is 71 divisions. A shunt of is connected parallel to galvanometer and value of R is adjusted such that main current remains the same. If the deflection in the galvanometer falls to 15 divisions then the resistance G of galvanometer is (in ohm)

Three long straight and parallel wires carrying currents are arranged as shown in figure. The wire 'B' which carries a current of 5A is so placed that it experiences no force. The distance of wire ' B ' from A is then
