Question

Moving charges and magnetic field notes only formula

Answer 1

Hi mate.


Thanks for asking this question.


Here is your answer,




Magnetic Field of a Moving Charge

Experiments show that the magnetic field of of moving charge can be expressed as:


$b \: = \frac{ {u}^{o} }{4\pi} \times \frac{q \: \times \: v}{ {r}^{2} }$

μo ≡ 4π × 10-7 N·s2/C2 is called the permeability of free space. The constant εo that is used in electric field calculations is called the permittivity of free space. Note that εoμo = 1/c2.





Thank you.
