One possibility for such a futuristic energy source is to store antimatter charged particles in a vacuum chamber, circulating in a magnetic field, and then extract them as needed. Antimatter annihilates with normal matter, producing pure energy What strength magnetic field in T is needed to hold antiprotons, moving at 22 x 10m/s, in a circular path 2./ m in radius? Antiproton have the same mass as protons but the opposite (negative) charge.

Explanation / Answer

For circular path

qvB=mv^2/r

B=mv/rq

Putting the values

v=2.2*10^7m/s

r=2.1m

We got

B=0.109T
