NEET Questions / Physics / Magnetic Effects of Current and Magnetism
A small compass is placed near the north pole of a bar magnet. In which direction will the north pole of the compass point?
Towards the north pole of the magnet
Away from the north pole of the magnet
Perpendicular to the axis of the magnet
The compass will not be affected
The magnetic field is strongest at which point of a bar magnet?
Center
Poles
Midway between the center and either pole
The field strength is uniform everywhere
Inside a bar magnet, the magnetic field lines travel from:
North pole to south pole
South pole to north pole
East to west
West to east
Breaking a bar magnet in half results in:
One magnet with only a north pole and another with only a south pole.
Two smaller bar magnets, each with a north and south pole.
Two pieces of non-magnetic material.
One smaller bar magnet and one piece of non-magnetic material.
Which of the following is NOT a property of magnetic field lines?
They form closed loops.
They originate from the north pole and terminate at the south pole outside the magnet.
They intersect each other.
Their density represents the strength of the magnetic field.
A short bar magnet is placed with its north pole pointing towards geographic north. The neutral point is located:
on the axial line of the magnet
on the equatorial line of the magnet
at the center of the magnet
at the south pole of the magnet
Two identical short bar magnets are placed at a distance apart with their axes perpendicular to each other. The magnetic field at the midpoint of the line joining their centers is:
\frac{\sqrt{5} \mu_0 m}{2\pi d^3}
\frac{2 \mu_0 m}{\pi d^3}
\frac{\mu_0 m}{2\pi d^3}
\frac{5 \mu_0 m}{2\pi d^3}
A bar magnet is cut into two equal halves along its length. The magnetic dipole moment of each half is:
