Question

Hi, can someone please give me a sketched example of an experiment where I can show or measure the distance and answer the question asked in Goals:

Thank you!

6.2 Magnetic interaction Goal: Investigate quantitatively how the magnetic force that a bar magnet and a current-carrying coil exert on each other depends on the distance between them Available equipment: Bar magnet, coil of wire, high-current, low-voltage power supply or 6V battery, connecting wires, Vernier force sensor, LabQuest interface, computer, protractor, support stand, right-angle clamp, rod for support stand, meter stick, tape, string

Explanation / Answer

Goal : Investigate quantitatively how the magnetic force that a bar magnet and a current-carrying coil exert on each other depends on the distance between them.

Available Equipments : Bar magnet, coil of wire, high current, low voltage power supply or 6V battery, connecting wire, Vernier force sensor, LabQuest interface, computer, protractor, support stand, right-angle clamp, rod for support stand, meter stick, tape and string.

Warning : Do not leave the voltage source ON after we finish the measurements.

I. Testing Experiment : Right hand rule

Think of how we can use this equipment to test the right hand rule for a direction of the force exerted by magnetic field on a current carrying wire. Also, think of what physical quantities could we determine using the scale -

Comments : Through this experimentation students will clearly observe that magnets do not need to be in contact with objects to exert a force and that the size of force is dependent on their distance from the paper clips.

It is important that students be able clearly articulate how distance affects the amount of force a magnet is able to exert on objects in their interpretation of an investigation results and that they clearly use the terms cause & effect in their discussions.
