Soft metals are used to create temporary magnets, which only become magnetic when subjected to an electric current or a permanent magnetic field. They get magnetized when they come into touch with a magnetic field. They eventually lose their magnetic properties when the magnetic field is removed. Paperclips, iron nails, and other things of a similar nature serve as temporary magnets.

What is a compass? How is a compass used to find directions?
Magnetic field lines never intersect each other because
There will be two directions of the field at the same point.
Feild lines repel each other
Field lines follow discrete paths only
If field lines intersect they create a new magnetic field within the existing fieldTwo parallel wires carry currents of 20 A and 40 A in opposite directions. Another wire carrying a current antiparallel to 20 A is placed midway between the two wires. The magnetic force on it will be
