Along wire lying along the x-axis carries a current of 3.40 a in the +x direction. there is a uniform magnetic field present, given by b=0.003i + 0.004j + 0.002k, where i, j, k are the unit vectors along the cartesian coordinate axes') in units of tesla. calculate the y-component of the magnetic force acting on a segment of wire of length l = 21.5 cm.

Explanation:

 Expression for magnetic force

F = L ( I X B )

B magnetic field and I is current

Here I = 3.4 i

B = .003i + .004 j + .002 k

F = 21.5 X 10⁻² x 3.4 i X ( .003i + .004 j + .002 k )

=( .2924 k - .1462 j )x 10⁻²

so y component of magnetic force = - 0.1462  x 10⁻² N

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
