This is called the motor effect. Electromagnetism works on the principle that moving charges generate a magnetic field. I will explain all these terms to you in detail. Here is what is done: If you have a bar of steel or iron (to be magnetized), simply connect a solenoid (a coil with multiple turns) to a D.C supply (current flows in one direction only). 0000004839 00000 n Step-1 : Read the Book Name and Author Name thoroughly. 22 The strength of the magnetic field depends on the current through the wire and the distance from the wire. Any magnetic/magnetized object has a North and South pole. Overall 1,2,3,4,5. (c) direction of force on a current carrying conductor in a magnetic field. Net flux through the surface = B dA = BAcos. Lecture notes -Magnetism and Electromagnetism. 2. One material (X) gets attracted to a magnet, but the second material (Y) repels the magnet. The point to note over here is that a force is applied on the coil (due to the current and the magnetic field) that allows it to rotate.

Shaping a wire to form a solenoid increases the strength of the If you heat the magnet past the Curie point (temperature above which the magnet becomes demagnetized), the magnet will start losing its magnetic properties. But why? But for now, here is what you should know: Magnetic materials are those materials that are attracted to a magnet (due to their magnetic properties). %%EOF /Length 8 The energy of the particle will. container.style.width = '100%'; Like poles repel, unlike poles attract.
