magnets bitch

E_feild=

V/d

voltage and distance

width and hallemf

E_force=B_force

E_field=B_field*V_d

electron drift speed

I=

NqV_dA

I=current

N=electron density per m³

q=1.6e-19

V_d=electron drift speed

A=cross sectional area

hall effect right hand rule

thumb in the direction of electron current and fingers in the direction of magnetic field, palm will be positive and back hand will be negative

magnetic flux=

B_field*Area*cos(theta)

flux theta

or 90- theta on the other side

V=

q/c

charge/capacitance

capacitor voltage

V_in(1-e^(-t/rc)

rhr for positive charge going into a magnetic field

index in direction of motion middle in direction of field resulting in thumb in direction of force, reverse for negative

force on a wire through a magnetic field

F=ILB

current lenght*field

force on a point charge moving through a magnetic field

F=QVB

charge * velocity * field

for a charged mass moving through a magnetic field

F_B=F_Centripical

F_B=QVB

F_Centripical=MV²/

velocity selector means

velocity wont change/ F_net=0

a point charge traveling through a velocity selector and magnetic field

Fmag=F_electric

in oppsite directions

F_electric

E_field * Q
