Find the magnetic field (positive magnitude only, no direction) at point p. i1 = 12.0 a r1=2.40 m i2 = 10.0 a r2 = 1.25 m

Sagot :

The magnetic field (positive magnitude only, no direction) at point p is further explained below.

B=1.89*10^{-6}

What is the magnetic field (positive magnitude only, no direction) at point p.?

Generally, the equation for magnetic field is mathematically given as

[tex]B= \frac{\mu0}{2\pi}*\frac{I1}{r1}[/tex]

Therefore

[tex]B1= \frac{2*10^{-7}(10)}{240}[/tex]

B1=1*10^{-6}T

and

[tex]B2= \frac{2*10^{-7}(10)}{1.25}[/tex]

B2=1*10^{-6}T

In conclusion,

[tex]B=\sqrt{B1^2+B2^2}[/tex]

B=1.89*10^{-6}
