#B=5963.3T#

Explanation:

We know that the force on a current carrying wire in a magnetic field is given by

#F=ILB#

Where
#F:# Force experienced by the wire.
#I:# Current in the wire.
#L:# Length of the wire.
#B:# Magnetic field.

In our case it is given that
#F=650N#
#I=0.545A#
#L=20cm=0.2m#
#:.650=0.545×0.2×B#
#:.B=5963.3T#
