The magnetic and electric fields are both similar and different. They are also inter-related.
Just as the positive (+) and negative (−) electrical charges attract each other, the N and S poles of a magnet attract each other.
In electricity like charges repel, and in magnetism like poles repel.
The magnetic field is a dipole field. That means that every magnet must have two poles.
On the other hand, a positive (+) or negative (−) electrical charge can stand alone. Electrical charges are called monopoles, since they can exist without the opposite charge.
Magnetism is a force that acts at a distance and is caused by a magnetic field. The magnetic force strongly attracts an opposite pole of another magnet and repels a like pole. The magnetic field is both similar and different than an electric field.

The ferrite is made of iron oxide and other ingredients. Generally can be divided into permanent ferrite, soft ferrite and rotating ferrite three.Permanent magnet ferrite, also known as ferrite magnet, is what we usually see the black small magnet.
