If you look from top of conductor carrying current with direction of current pointing towards you, direction of the magnetic field will be in counterclockwise direction around the current carrying wire.
Hence D is the correct option.
Hope this helps!
Answer:
Explanation:
We are given that
Energy difference,
We have to find the magnitude of B.
Bohr magneton=
We know that magnetic field ,B=
By using the formula
Hence, the magnitude of B=
Frequency = (speed) / (wavelength)
= (3 x 10⁸ m/s) / (300 m)
= 1 x 10⁶ per sec
= 1 mHz
This frequency is the " 1000 " or " 100 " that's marked
in the middle of your AM radio dial.
If there's an AM station in your city that broadcasts on 1000 kHz
and you tune your radio to it, you're picking up radio waves
that are 300 meters long. (about 0.19 of a mile)
