The magnetic field lines are more intense at either of the poles of the magnet . It is equally strong at north and south pole of the magnet . Since we know that how many magnetic field lines pass through a given space tells about the magnetic field strength. The more field lines within a certain fixed volume, the greater the strength of the magnetic field. In the given diagram the number of field lines are maximum around the poles . Hence the magnetic field is more intense at the poles.

Moving charges will produce a local magnetic field, but the reverse is also true a changing magnetic field will similarly induce charges to move (ie. produce current). Consider a magnet moving into a coil of wire: A spinal coil of wire with many closely-spaced tums this is called a solenoid is connected to a micro-ammeter as shown in the diagram above. As the magnet moves into the coil, any induced current will be measured by the micro-ammeter. Question On the...
