F=q(v x B)

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)

B=(uo)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)=u0Ip

r^=r/|r|

Good luck to everyone tomorrow
