Compact demonstration to show induced magnetic fields
• Three induction demonstrations at once
• Includes three compasses
• Clear backing makes it useful on an overheadA clear plastic frame holds three different connecting wire set ups: a straight wire, a single loop, and a solenoid. The thick wires allow users to pass through higher currents (1 A) than thinner wires, creating a more noticeable induced magnetic field. A perfect way to demonstrate how a magnetic field is produced, and an easy way to introduce the hand rules for magnetic fields.
