6.8 know that an electric current in a conductor produces a magnetic field around it
6.9P describe the construction of electromagnets (Triple)
6.10P draw magnetic field patterns for a straight wire, a flat circular coil and a solenoid when each is carrying a current (Triple)
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 (Triple)
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.
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.
6.14 describe how the force on a current-carrying conductor in a magnetic field increases with the magnitude and direction of the field and current.

Relay - Explained and animated
A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such ...as solid-state relays. Relays are used where it is necessary to control a circuit by a separate low-power signal, or where several circuits must be controlled by one signal[+] Show More

A short video that explains the physics of a speaker and how it relates to the motor effect (Lorentz force) CORRECTION: A number of comments stated there is only one magnet ...(not two as stated) That is true. The ring magnet has a top and bottom polarity, that with the plates (a center plate and a top plate) set up one polarity on the outside and the the other polarity on the inside pole) So apologies for my error on the magnet itself. However, the explanation of its working is nonetheless correct.
