This is the longest section of this Physics course. It begins with concepts like magnets and their types, magnetic poles, field force and moment, then it continues with some important laws of electromagnetism such as Ampere's, Faraday's and Lentz Law. Magnetic force acting in various situations such as in a long current-carrying wire, whether moving or not, inductance and induction, self-inductance, induced current and induced electromotive force, induced electric fields, RL and RLC circuits, energy stored in magnetic fields, direct and alternating current, energy stored in magnetic field and power in AC circuits are other concepts discussed in this section. Moreover, some practical applications of electromagnetism such as electric magnet, electric motor, electric generator and transformer (both types) are explained, illustrating them with examples. At the end of section, all relevant equations of electromagnetism known as Maxwell Equations are provided in a summative way.
In addition to the Magnetism tutorials, we also provide online Magnetism Calculators which allow you to calculate specific Magnetism formula in support of the tutorials or to check and verify your own calculations in support of your homework, coursework or thesis.
The following Physics Calculators are provided in support of the Magnetism tutorials.
