So my professor has been using an equation to find the magnetic field of a wire, but the equation is not present in the textbook. it is
B = μI/(4πa)(cosθ_1 - cosθ_2)
The theta is is an interior angle and theta 2 is an exterior angle. Anyone know what I'm talking about?
B = μI/(4πa)(cosθ_1 - cosθ_2)
The theta is is an interior angle and theta 2 is an exterior angle. Anyone know what I'm talking about?
