A flat, circular loop has 15 turns. The radius of the loop is 14.0 cm and the current through the wire is 0.55 A. Determine the magnitude of the magnetic field at the center of the loop (in T). T

0.000037007 T

Explanation:

Current in the loop I = 0.55 A

Radius of the loop = 14.0cm = 0.14m

Number of turns in coil = 15turns

B = μ• nI/2R

= 4π×10^-7T.m/A × 15× 0.55/2(0.14)

= 0.000001256×15×0.55/0.28

= 0.000010362/0.28

B = 0.000037007 T

infared light

700 nanometers

Infrared radiation extends from the nominal red edge of the visible spectrum at 700 nanometers (nm) to 1 millimeter (mm). This range of wavelengths corresponds to a frequency range of approximately 430 THz down to 300 GHz. Below infrared is the microwave portion of the electromagnetic spectrum.

ultraviolet light

Ultraviolet (UV) is electromagnetic radiation with wavelength from 10 nm (with a corresponding frequency of approximately 30 PHz) to 400 nm (750 THz), shorter than that of visible light but longer than X-rays.
