How do you find the strength of an electromagnetic field?
What would be the strength of the magnetic field if the electromagnet was 200 cm, has 10 amps running through it, and has 400 coils?

The magnitude of the electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them.

What cases do kirchoff's law not apply?

Re: Circuit Lab B/C
No, there are some cases where they don't apply. With KVL, it doesn't apply with a varying magnetic field, and with KCL, it doesn't apply when the voltage source has a very high frequency. Anyways, your turn!UTF-8 U+6211 U+662F wrote:MattChina wrote:What cases do kirchoff's law not apply?They always apply?

Calculate the electric field strength 1 micrometer from a proton (e=1.6e-19 C).
If a proton is moving east at 300 m/s and experiences an acceleration of 2.6e10 m/s^2 south, what is the strength and direction of the B-field (the mass of a proton is 1.67e-27 kg)?
