About This Product
With compasses set in a ring round the straight conductor, switching on the current turns the needles into a circle, and the right-hand thumb rule predicts their direction. A Hall effect probe on the slider bracket, moved outward step by step, measures how field strength falls with distance, and comparing the wire, loop and solenoid shows how conductor shape changes the field.

Frequently Asked Questions
What current does the Ampere Law Apparatus take?
Up to 5 Amperes DC continuously, and up to 8 Amperes for short durations. Conductors heat up at high current, so long runs at high current should be avoided.
Is a gaussmeter included?
No. The apparatus has a mounting bracket for a Hall effect gaussmeter probe; 4 plotting compasses are included.
