Question 125: Magnetism and Matter

Question

A triangular shaped wire carrying $$10 \mathrm{~A}$$ current is placed in a uniform magnetic field of $$0.5 \mathrm{~T}$$, as shown in figure. The magnetic force on segment $$\mathrm{CD}$$ is
(Given $$\mathrm{BC}=\mathrm{CD}=\mathrm{BD}=5 \mathrm{~cm}$$.)

Accepted Answer

$$\overrightarrow F  = i\overrightarrow l  	imes \overrightarrow B $$
$$ = ilB\sin 60^\circ $$
$$ = 10 	imes {5 \over {100}} 	imes 0.5 	imes {{\sqrt 3 } \over 2}$$
$$ = 0.2165$$ N

Answer

0.126 N

Answer

0.312 N
