... completely, the retentivity BR must be reduced to zero. To demagnetize a magnetic material completely, the retentivity BR must be reduced to zero. A practical way to do so is to magnetize and demagnetize the material with a decreasing hysteresis loop. This method of demagnetization is called degauss ...

... His work with electricity and magnetism led him to realize that while a current creates a magnetic field, a magnetic field can be used to create a current. Faraday’s Law describes another form of the connection between magnetism and electricity. We encountered the first connection when we studied Am ...

Magnetic Effect of Electric Current
... Like poles of magnets repel each other while unlike poles of magnets attract each other. Similar to other effects; electric current also produces magnetic effect. The magnetic effect of electric current is known as electromagnetic effect. It is observed that when a compass is brought near a current ...

... (b) Here we will use Ampere’s law, which says that B symmetry of the wire, the magnetic field circles around inside the wire. So, we choose a circle of radius r ≤ R for our Amperian loop. Since the magnetic field is constant H along that loop, and points along d~s, the left-hand side of Ampere’s ~ · ...
