The magnetic field at the center of a 0.50-cm-diameter loop is 2.9 mt . part a what is the current in the loop? express your answer in amperes. i i = nothing a submitrequest answer part b a long straight wire carries the same current you found in part a. at what distance from the wire is the magnetic field 2.9 mt ? express your answer in meters. l l = nothing m submitrequest answer provide feedback next

A)I=11.35 A

B)R=0.079 cm

Explanation:

Given that

For loop:

d= 0.5 cm  ,r=0.25 cm

B=2.9 mT

A)

We know that magnetic filed in loop given as

   -----1

Now by  putting the values

I=11.35 A

B)

Magnetic filed for wire given as

   ----2

Given that B and I is same so we can say that

Form equation 1 and 2

π R= r

R=0.079 cm

answer: good job it's all correct !

explanation:

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.
