00:00.000 --> 00:11.323
We will observe the interaction between electric current and magnet (compass)!

00:11.323 --> 00:20.101
I use an adjustable intensity generator designed to work in cct. The compass indicates the North

00:20.101 --> 00:27.726
At closing: 0.23 Amperes, a slight deviation is observed

00:27.726 --> 00:35.217
By increasing the intensity, the deviation of the needle increases

00:35.217 --> 00:44.699
At 12 A, one approaches 90 ° (unattainable value because more attraction to 90 °)

00:44.699 --> 00:52.453
The compass suffers a magnetic field due to the flow of electric current

00:52.453 --> 01:06.143
Indeed, copper does not influence the compass, except when the current flows!

01:16.166 --> 01:28.363
The sending of pulses demonstrates the power of the magnetic field induced in a conductor subjected to an electric current!
