About Me

I blog about my daily learnings in Physics class and I also throw in a haiku here and there.

Right Hand Rules; 1 and 2

RHR #1 is for conductors and it used with conventional current (+ to -). To execute the right hand rule you simply point your thumb in the direction of the current and curl your fist. The direction which your fingers are pointing towards is the direction of the magnetic field. 


RHR #2 is used for coils and conventional current. You wrap your hand around the coil with your fingers pointing in the direction of the current and your thumb should then point to the direction of the magnetic field B, or N (north). 



ooo00o0o0o another haiku;


Birds and sharks have died,
due to Earth's magnetism.
Humans feel nothing.
