#4abcd
Two currents run in parallel with I2 = 211.
The following statements regard the interaction between the
two currents, where F and F2 are the magnitude of the mag-
netic force on I and I2, respectively. Identify the statements
as either true or false. For each false statement, you need
I, = 4.2 A
:0.7m
to explain why it is false.
I = 2.1 A
(A) The force on I points toward I2 and F, = F2.
true
false
Why:
(B) The force on I1 points toward I2 and F = 2F.
true
false
Why:
(C) The force on I1 points away from I2 and F1 = 2F2.
true
false
Why:
(D) There are no forces between the two currents.
