the wire in (figure 1) carries current i2i2, which is 20 times the current i1i1 of the loop; the direction of the current in the wire is shown. the magnetic field in the center of the loop is zero. the radius rr of the loop is 1.4 cmcm.

The amount of current flowing through the loop's center is [tex]I_{1} = \frac{\pi DI_{2} }{R}[/tex]

Is a loop's magnetic field zero in its center?

  • At the Loop's core, the magnetic field is empty.
  • B=[tex]m[/tex]0I2R(at center of loop), B =[tex]m[/tex] 0 I 2 R(at center of loop), where R is the loop's radius, gives the magnetic field strength at the loop's center.
  • In a circular electric current loop, the magnetic field is more concentrated in the center than on the outside.
  • In the absence of a conducting wire, the magnetic field's strength at a distance decreases inversely with distance.
  • Since circle one (A) has the smallest radius, its magnetic field is greatest at its center.
