Edexcel IGCSE Physics Lecture 27 - Electromagnets Part 2

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

Specification Point 6.9P - Describe the construction of electromagnets.

Specification Point 6.10P - Draw magnetic field patterns for a straight wire, a flat circular coil and a solenoid when each is carrying a current.

Specification Point 6.11P - Know that there is a force on a charged particle when it moves in a magnetic field as long as its motion is not parallel to the field.

Specification Point 6.17P - Describe the structure of a transformer, and understand that a transformer changes the size of an alternating voltage by having different numbers of turns on the input and output sides.

Specification Point 6.18P - Explain the use of step-up and step-down transformers in the large-scale generation and transmission of electrical energy.

Specification Point 6.19P - Know and use the relationship between input and output voltages and the turns ratio for a transformer.

Specification Point 6.20P - Know and use the relationship between input power and output power.
