Answer:
Check the explanation
Explanation:
800A stands for a current of 800 Ampes and 900Hz stand for the frequency (the change in the electric field with time) of 900 Hz. In this video footage they’re trying to raise the 1 kg plate, and the major factor that is in charge in lifting the plate is the magnet field that is present. So the whole purpose of this experiment is attempting to produce a big enough magnetic force in order to lift the plate.
From the equation, we are aware that the bigger the current (800A) the bigger the magnetic force. Also, the bigger the frequency, the bigger the change in the electric field. therefore producing a bigger magnetic field and force. these figures have to be really large or larger enough to produce a powerful magnetic force strong enough to lift the plate.
0.5×10=0.50 or 1/2
