Product Description

Learn basic circuit principles and study electricity and magnetism by experimenting.

This kit makes a great gift for kids to learn AND understand the science behind electricity and magnetism.

A great electronic STEM kit for high school students (10th, 11th, 12th grade) to enhance what is learned from physics class

Easy enough for junior students (7th, 8th, 9th grade) and children to explore in advance and get interested in physical science

Magnetic fields and magnetic poles

List of materials: bar magnet, paper clip, U-shaped magnet, iron filings, A4 paper, polystyrene plate, basin

Practical activity:

Search for magnetic fields:

1, Place a piece of paper over a magnet (this prevents iron filings from sticking to the magnet).

2, Sprinkle some iron filings on the paper.

3, Gently tap the paper to spread the filings.

4, Observe and record the results.

Identify the magnetic poles:

Use a magnet to slowly approach the paperclip and observe which part will attract the paperclip.

All magnets have two ends where the magnetic field is strongest—— a north pole and a south pole. The poles are named this way because if a magnet floats in water or is suspended by a rope tied around its middle, it will align in a north-south direction, consistent with the Earth’s magnetic field.

How to make an electromagnet?

You will make an electromagnet by wrapping the magnetic wire around an iron nail.

When wrapping the wire around the nail, make sure you wrap the wire in one direction only.

Test how varying the design affects its strength: add more turns of wire to form a stronger magnet.

Use a power bank instead of a single battery for more power.

(Use wire strippers, sandpaper or a knife to carefully scrape the insulation from both ends of the magnet wire. This will help the wires conduct power.)

Uses of Electromagnet – Electric Bell

List of materials: Electric bell, battery, wire, switch

Practical activity:

1, as shown on the right, connect the circuit.

2, close the switch to turn on the circuit.

How does an electric doorbell work?

When the switch is closed, an electric current flows from the battery through the electromagnet. It creates a magnetic field that attracts the arm wrestling of the clapper, pulling it to strike a bell.

This opens a pair of electrical contacts attached to the clapper arm, interrupting the current to the electromagnet. The magnetic field collapses and the clapper moves away from the bell.

This closes the contacts, allowing current to flow back to the electromagnet, so the magnet pulls the clapper to strike the bell again. This cycle repeats and the bell rings continuously.

What is an engine?

A dictionary describes “a motor is a machine that converts electrical energy into mechanical energy”. In other words, electrical energy is “battery” and mechanical energy is “rotation”.

The instruction manual contains several experiment pictures and user guides, LED connection, magnetic fields and magnetic poles, Fleming’s right/left hand rule and makes a simple electromagnet, making electric bells , engine construction and the use of hand generators Note: 3 AA batteries required. Recommended from 8 years old. Young children should be under the supervision and guidance of parents.
