` $$ T ~=~ 2 \, \pi \frac{ \class{brown}{m} }{ |q| \, \class{violet}{B} } $$ `

` $$ T ~=~ 2 \, \pi \frac{ \class{brown}{m} }{ |q| \, \class{violet}{B} } $$ `

` $$ \class{green}{F} ~=~ q \, \class{blue}{v} \, \class{violet}{B} $$ `

In this video you will learn how to determine the direction of the Lorentz force using left/right hand rule and how this force is calculated and related to the centripetal force.

` $$ U_{\text H} ~=~ A_{\text H} \, \frac{I \, \class{violet}{B}}{d} $$ `

Explanation of what the Hall effect is, how exactly the Hall voltage is generated and how you can calculate it and the Hall constant.

` $$ U_\text{H} ~=~ \frac{1}{n \, q} ~ \frac{I \, \class{violet}{B}}{d} $$ `
