This durable variable gap magnet is fantastic for demonstrating and researching electromagnetism (and induced currents, too!). Magnet measures 5-1/4 L x 4-1/4 H x 2 W inches. Each screw is 3 inches long with a 1 inch diameter. The field strength can be adjusted between 100 and 7500 Gauss and the screws can be varied between 2/5 and 8-1/2 centimeters. The supplied flat pole pieces (measuring 2 x 1 x 1/8 inches) can provide a more uniform field when necessary.
