Give this one a try later!
When a charged particle (electron) exhibits motion, a corresponding
magnetic field is induced
What does the computer do?

Process information
Can resistive magnets be used in either vertical or •horizontal field systems?
Give this one a try later!

Give this one a try later!
Vertical field magnets
Horizontal field magnets
How do you increase field strength and homogeneity in vertical magnets?
Give this one a try later!
Field strength and homogeneity can be increased by reducing gap
between two magnets
