Transcript of PH 223 32:1-3

A proton moves along the x-axis with a velocity v =1.0 x 10 m/s. As it passes the origin, what are the strength and direction of the magnetic field at the (x,y,z) positions
a (1 cm, 0,0)
b (0, 1 cm, 0)
c (0, -2 cm, 0)

A proton is passing the origin. The magnetic field at the (x,y,z) position (1mm, 0,0) is 1.0 x 10 j T. The field at (0, 1 mm, 0) is -1 x 10 i T. What are the speed and direction of the proton?
Cross product. What is ( 2, 4, 5) x ( -2, 3, 0)
what is the angle between these two vectors
what is the length of the resulting vector?

"SO ...if magnetism is caused by current... what is moving in permanent magnets? "
"It states in the book that the earths magnetic field could result from current in its molten iron core. How would these currents arise?

What are some practical uses for magnets?"
"Can we go over how you take the cross product of 2 vectors."
