: In MKS units: T is Tesla, A is amperes, V is volts.
c) Using an equation for magnetic field: the units of µo can beexpressed as
T-m/s
T-s/V
T-A/m
T-A/V
T-m/A
A/T-m
A-m/T
T-s/m
A/T-s
T-s/A
d) The instructions tell you to zero the magnetic field sensorbefore turning it up. If you do not do this, then for eachtrial:
the magnetic field sensor readings will be off by a fixedamount
there will be random fluctuation in the power supply votage, and inthe currents
there will be random errors in the magnetic field sensorreadings
the current might spike, and burn out the coil
voltages from the power supply, and the currents, will be off by afixed amount
