A transformer is an electrical device that takes in electricity at a higher voltage and outputs it at a lower voltage. It works by using the principles of electromagnetism - an alternating current running through coils wrapped around an iron core creates an alternating magnetic field, which induces a current in another set of coils wrapped around the same core. The fewer coils on the output side result in a lower output voltage than the input voltage, "stepping down" the voltage. Transformers are commonly seen on utility poles and are used to safely reduce high-voltage power for use in homes and devices.
Hypothesis: The 4 factors which can affect the strength of an electromagnet are the type of core used, the number of turns of wire, the magnitude of the current used and the shape of the solenoid.
Aim: To investigate the factors which affect the strength of an electromagnet.

Electromagnetic induction builds on the concept of magnets and magnetic fields in grade 10. Most of the work covered here is quite clear and straight forward.
Its a simple project for class 12th science students. This project is collected from various sources including Google, Wikipedia and Slideshare, Youtube and many more.
