Edexcel IGCSE Physics Lecture 26 - Electromagnets Part 1

Powerpoint lecture covering the following in a modern, concise format:

Specification Point 6.8 - Know that an electric current in a conductor produces a magnetic field around it.

Specification Point 6.12 - Understand why a force is exerted on a current-carrying wire in a magnetic field, and how this effect is applied in simple D.C. electric motors and loudspeakers.

Specification Point 6.13 - Use the left-hand rule to predict the direction of the resulting force when a wire carries a current perpendicular to a magnetic field.

Specification Point 6.14 - Describe how the force on a current-carrying conductor in a magnetic field changes with the magnitude and direction of the field and current.

Specification Point 6.15 - Know that a voltage is induced in a conductor or a coil when it moves through a magnetic field or when a magnetic field changes through it and describe the factors that affect the size of the induced voltage.

Specification Point 6.16 - Describe the generation of electricity by the rotation of a magnet within a coil of wire and of a coil of wire within a magnetic field, and describe the factors that affect the size of the induced voltage.
