Introduction: In our day to day life, electricity and magnetism are related to each other. We can experience the magnetic effect of electric current in wiring circuits of our home appliances. For example: take a small compass and bring closer to current carrying wire, surprisingly you can see the deflection of compass. It is because, the current carrying conductor produces magnetic field, the result of which the compass deflects. Similar discovery was made by Oersted in 1800.
Magnetic effect of current: The current flowing through a straight conductor has magnetic field in the form of concentric circles encircling it. Its direction can be understood by Maxwell's cork screw rule and Fleming left hand rule. It increases with increase in number of turns of coil in solenoid and can be employed to magnetize materials. Light and electromagnetic waves are produced as a result of deflection in electromagnetic waves perpendicular to each other.
Applications: The magnetic effect of current has wide application such as cyclotron, galvanometers,ammeters, voltmeters, generators, motors, induction stoves, communications and MRI scans.
Conclusion: We have everyday application of electromagnetic effects in real life applications like cell phone signals, internet, circuits, fans, bike speedometers etc.. Such examples should be known by everyone as primary knowledge. The world thanks to scientist Maxwell for his remarkable contribution in unification of electricity and magnetism.
