Answer:
a. True
b. True
c. True
Explanation:
A constant magnetic field can produce an electric current in a nearby conducting wire
The magnetic field produce current so:
[tex]\beta=u*\frac{N}{L}*I[/tex] I=current TRUE
A changing magnetic field can produce an electric current in a nearby conducting wire
The magnetic field produce current so:
[tex]\beta=u*\frac{N}{L}*I[/tex] I=current TRUE
The induced EMF in a conducting wire is proportional to the rate at which the magnetic field changes.
[tex]E=N*\frac{dP}{dt}[/tex]
dP=rate magnetic field changes TRUE
