A strong bar magnet is placed vertically above a horizontal wooden board. The magnetic lines of force will be:
(a) only in horizontal plane around the magnet
(b) only in vertical plane around the magnet
(c) in horizontal as well as in vertical planes around the magnet
(d) in all the planes around the magnet
The figure given below shows the magnetic field between two magnets:
Copy the diagram and label theother poles of the magnets.
Which is the weaker magnet?
Explain the following :
When two pins are hung by their heads from the same pole of a magnet, their pointed ends moves apart.
Figure. shows a bar magnet placed on the table top with its north pole pointing towards south. The arrow shows the north-south direction. There are no other magnets or magnetic materials nearby.
What is the magnitude of the magnetic field at each neutral point? Give a reason for your answer.
Draw diagram showing the arrangement of the lines of force for a single magnet.
State whether true or false. If false, correct the statement.
Magnetic field lines always repel each other and do not intersect.
Magnetic lines of force never ______ each other.
A charge moving in a magnetic field, in a direction other than the direction of the magnetic field, experiences a force. It is called the ______ force.
Can two magnetic lines of force intersect? Justify your answer:
Assertion (A): Magnetic field lines never intersect each other.
Reason (R): If they intersect, then at the point of intersection, the compass needle would point towards two directions, which is not possible.
