Physic coursework on electromagnet Aim: To investigate how the strength of an electromagnet change as you varies the number of turns of the coils. Introduction: In this experiment, we are going to design a circuit to test what factors can make the electromagnet stronger and how we can do that. Electromagnet is a solenoid (coil of wires) with an Iron core. When an electric current flowing through a wire, it creates a magnetic field in the region of the wire. This is a way how magnetic created, which is known as electromagnetism. Solenoid is a long coil made up of a number of turns of wire. When a current flows through solenoid each turn acts as a single coil and produces a magnetic field. This diagram shows the field pattern around the solenoid. There are some methods to increase the strength of the electromagnet, which are: - 1. Increase the size of the current. 2. Increase the...
