Three long, straight parallel wires carrying current, are arranged as shown in figure. The force experienced by a 25 cm length of wire C is
Text Solution
Verified by ExpertsThe correct answer is:
C
The magnetic field due to wire 
at wire 
is
which is directed into the page.
The magnetic field due to wire 
at 
is
which is directed out of the page.
Therefore, the net magnetic field at the position of the wire 
is
The force on 25 cm of wire 
is
