Electromagnetic Induction And Its Effect On The Strength Of An Electromagnet
University Electromagnetic Induction
This report is a description of a lab experiment whose aim is to explore the influence of the number of coils on the strength of an electromagnet. The target is to find out whether the magnetism increases with the alteration of the number of turns in an electromagnetic coil.
Electromagnetism is the transformation of electrical current into a magnet, which is in turn induced into a ferromagnetic materials, causing them to behave in similar manner as magnets. The only difference between electromagnets and permanent magnets is that the former loses its magnetic properties while the latter retains them. It is common knowledge of basic physics that electricity is able to behave like a magnet. Conversely, a magnet has the ability to produce electricity. In the former case, the movement of current, while in the latter, it is the change in the magnetic flux that cuts across the coil.
The principles of electromagnetic induction were discovered by Hans Christian Ørsted, a Danish physicist. He made the observation that current has the capability to produce magnetic fields, in 1820, which opened up the field of electromagnetism, for other European physicists. Current moving in a particular direction in a single wire produces concentric magnetic fields in accordance with the Oersted’s law, which is popularly referred to as the right hand rule. The magnetic field’s direction at a point is…
