Question

A constant magnetic field can produce an electric current in a nearby conducting wire. False True A changing magnetic field can produce an electric current in a nearby conducting wire. True False The induced EMF in a conducting wire is proportional to the rate at which the magnetic field changes. False True

Answer 1

a. True

b. True

c. True

Step-by-step explanation:

A constant magnetic field can produce an electric current in a nearby conducting wire

The magnetic field produce current so:

`\beta=u*(N)/(L)*I` I=current TRUE

A changing magnetic field can produce an electric current in a nearby conducting wire

The magnetic field produce current so:

`\beta=u*(N)/(L)*I` I=current TRUE

The induced EMF in a conducting wire is proportional to the rate at which the magnetic field changes.

`E=N*(dP)/(dt)`

dP=rate magnetic field changes TRUE
