"Electricity and Magnetism" Energy PPT Teaching Courseware

Part 1: Importing new lessons

More than 100 years ago, people's understanding of electricity and magnetism was very limited. By chance, Danish scientist Oersted discovered a secret about electricity and magnetism. Do you want to know what this secret is? Today we will relive that great moment in history.

Electricity and Magnetism PPT, Part 2 Content: New Lesson Learning

In 1820, Danish scientist Oersted accidentally brought an electrified wire close to a compass during an experiment and discovered a strange phenomenon. It is this phenomenon that opens the door for mankind to utilize electrical energy on a large scale.

Assemble a circuit that lights up a small light bulb. Do you see if the light bulb lights up? Recall the path electricity takes in a circuit.

Starting from the positive terminal of the battery, it flows through the circuit and back to the negative terminal of the battery.

Material preparation:

Batteries, battery box, small light bulb, lamp holder, wires (one of which is longer), compass, stranded insulated wire about two meters long.

Put a compass on the table. What direction does the compass point after the needle stops swinging? Straighten the wire in the circuit over the compass needle in the same direction as the magnetic needle points. What happens to the compass when the current is turned on? What happens to the compass after the current is disconnected? Repeat this several times, and what is the result?

Electricity and magnetism PPT, part three: conclusion summary

1. Electric current can produce magnetism.

2. Energizing a straight wire causes the compass needle to deflect.

3. An energized coil deflects the compass needle.

4． Place the coil upright, with the flat surface of the coil close to the compass, or place the coil on the compass so that the pointer deflects at the maximum angle.

Electricity and Magnetism PPT, Part 4: Classroom Exercises

(1) Multiple choice questions

1. Electricity and Magnetism ( )

A. It’s relevant B. It doesn’t matter C. It’s dispensable

2. If the circuit is short-circuited, the current will be ( )

A. Very weak B. Very strong C. Disappear

3. When the compass is at rest, the direction indicated by the pointer is ( ).

A. Pointing to the northwest B. Pointing to the north and south C. Pointing to the east and west

(2) Judgment questions

1. Electrical conductors can produce magnetism. ( )

2. When doing experiments, wires cannot be connected in the circuit for a long time. ( )

3. Increasing the current in the wire does not affect the deflection of the small magnetic needle. ( )
