A wire along the x-axis carries a current of `3.50A` in the negative direction. Calculate the force (expressed in term of unit vectors) on a `1.00cm` sectioin of the wire exerted by these magnetic fiels.
a. `B=-(0.65T)hatj b. `B=+(0.56T)hatk c. `B=-(0.31T)hatj`
d. `B=_(0.33T)hati-(0.28t)hatk` e. `B=+(0.74T)hatj-0(0.36T)hatk`

Text Solution

Verified by Experts

`because i=3.5a`
`I=(-10^-2hatj)`
Now, apply `F=i(IxxB)` in all parts.
