Magnetism Equation Dump

F=q(v x

R=(mv)/(qB) for a point charge in a magnetic field

v=E/B (speed at which an object must be traveling not to feel a net force in a magnetic and electric field)

T(torque)=NIA x B

F=I(L x

B=(u_o)q/(4Pi)*(v x r^{^})/r²

B=u₀nI(for solenoids)

B=u₀*2I/(4Pi*R) (Due to single straight wire)

B=u₀*NI/(2Pi*R) (between the inner and outer radius of a toroid)

Integral over closed surface of (B dA)=0

Integral over closed curve of (B dl)=u₀I_p

r^{^}=r/|r|

Good luck to everyone tomorrow
