"Electricity and Magnetism" Energy PPT Courseware 2

In 1820, the Danish scientist Oersted accidentally brought a current-carrying wire close to a compass during an experiment, and discovered a strange phenomenon. What phenomenon did he discover?

friendly reminder

(1) Hold the wire with both hands and straighten it against the compass in the same direction as the magnetic needle.

(2) After the compass comes to rest, close the switch and turn on the current. Observe whether there is any change in the compass? Turn off the switch to cut off the current and observe what happens to the compass?

(3) Repeat it several times, and what is the result?

Circuit short circuit experiment

Tip: If the circuit is short-circuited and the current is very strong, the battery will heat up quickly. So it can only be connected once and disconnected immediately, and the time cannot be long.

Circuit short circuit experiment

hint:

(1) Remove the small bulb and lamp holder, but keep the switch;

(2) Everything is ready, power on, and the switch can be released with one touch.

friendly reminder

Replace a wire in a circuit with a coil

(1) The coil and the magnetic needle are in the same direction. Compared with a coil or a wire, which one causes the magnetic needle to deflect at a greater angle?

(2) The coil can be placed flat or vertically. The magnetic needle can be placed inside the coil, or placed in front, back, left, right, etc., and the direction of deflection of the magnetic needle can be observed and recorded. Which method will deflect the magnetic needle at the largest angle?
