The sum of all magnetic fields adds up to zero at the :

1. north pole
2. south pole
3. equator
4. neutral points

In a uniform magnetic field, the field lines are:

1. curved
2. parallel and equidistant straight lines
3. parallel, but non-equispaced straight lines
4. nothing can be said.

The magnetic field lines of the earth are …………… to the earth's surface near the magnetic poles and …………… to the earth's surface near the magnetic equator.

1. parallel, normal
2. normal, parallel
3. normal, normal
4. parallel, parallel

The direction of a magnetic field at a point on a magnetic field line is given by :

1. a tangent at that point
2. a normal bisector at that point
3. both tangent and normal bisector at that point
4. none of the above
