Like poles attracts and unlike poles repel. This statement is true for
only bar magnet
only horse shoe magnet
all type of magnet
only magnetic needle
Which of the following is a vector quantity?
Magnetic field
potential difference
distance
none of these
The magnetic field lines in the vicinity of the magnet are
Curved
Straight line
Discrete
Parabolic
When we cut a magnet into two equal parts, then what is its strength of each part?
Equal to the strength of the original magnet
Half of the strength of the original magnet
Double the strength of the original magnet
1/3 of the strength of the original magnet
For a magnet, the magnetism is minimum at
the poles
the middle point
along the equater
none of the above
The magnetic field lines at distant points are
Parallel lines
Anti parallel lines
Curved lines
Hyperbolic curves
If the length of a magnet is L, then the effective length of the magnet is
6 L
In a uniform magnetic field, the field lines are
curved
parallel equidistant straight lines
parallel but non equispaced straight lines
nothing can be said
The two poles of a magnet have
same strength
different strength
cannot be predict
The resultant magnetic field at the neutral point is
1
2
zero
can't be predict.
