Unformatted text preview: 1. A wire is attached to two springs with a combined spring constant k. The wire
is partially located in a uniform magnetic ﬁeld Bo directed out of the page
over a length L. A current I is applied to the wire which causes the wire to ‘ deﬂect by a distance x.
a. [2 pts] What is the direction of the magnetic ﬁeld at point P produced
by the current in the wire? Draw it on the diagram.
