Question

Problem 4 Two electric blankets heating systems are (viewed from to I-1 A, there intensity above the field intensity and why? proposed as shown in Figure A and B above). Suppose that in either case, the current in each wire is equal are N-100 wires and the length d-2 m. Calculate the magnetic field in each case. Which system produces a lower magnetic Note: This solution was proposed for electric blankets when health concerns due to magnetic fields arose. Figure B Figure A MATLAB clear all; cle I-1; N-100, d-2; Ha- %find Ha for Figure A %find Hb for Figure B

Explanation / Answer

Given data is

N=100:

D=2:

I=1:

the formula is H=NI/D

substitutte above values in the formula

H=N I/D

=100*1/2

H=50

Hence the required answer is H=50.
