The magnetic field at the center of a 1.40-cm-diameter loop is 2.50 mt . part a) what is the current in the loop?
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 2.50 mt ?

Explanation:

It is given that,

Diameter of loop, d = 1.4 cm

Radius of loop, r = 0.7 cm = 0.007 m

Magnetic field,

(A) Magnetic field of a current loop is given by :

I is the current in the loop

I = 27.85 A

(B) Magnetic field at a distance r from a wire is given by :

r = 0.00222 m

Hence, this is the required solution.

radial fractures in a piece of glass look most like which of the following?

a. spokes of a wheel

b. a circle

c. a zig zag

d. none of the above

the correct answer is a. spokes of a wheel

hope this (:
