PHXII04:MOVING CHARGES AND MAGNETISM

362686 The incorrect statement regarding the lines of force of the magnetic field \(B\) is

1 magnetic intensity is a measure of lines of force passing through unit area held normal to it.
2 magnetic lines of force form a close curve.
3 inside a magnet, its magnetic lines of force move from north pole of a magnet towards its south pole.
4 due to a magnet, magnetic lines of force never cut each other.
PHXII04:MOVING CHARGES AND MAGNETISM

362687 A magnetic field can be produced by

1 A changing electric field
2 A moving charge
3 Both of these
4 None of these
PHXII04:MOVING CHARGES AND MAGNETISM

362688 Magnetic field at the centre of a coil in the form of a square of side 2\(cm\) carrying a current of 1.414 \(A\) is:

1 \(8 \times {10^{ - 5}}\;T\)
2 \(18 \times {10^{ - 5}}\;T\)
3 \(1.5 \times {10^{ - 5}}\;T\)
4 \(6 \times {10^{ - 5}}\;T\)
