Question

To describe the effect of this electric field on the rod, we need to find the EMF E. We take as a reference direction the path from end a to end b (i.e., moving along the positive y axis). The EMF is then negative if the induced electric field points in the −j^ direction.

Answer 1

Answer:

The effect of this electric field on the rod, we need to find the EMF E. We take as a reference direction the path from end a to end b wjll be as follows;

Express the relation for emf

E = Blv

Here, B is the magnetic field

l is the length of the rod

v is the speed tithe

The negative sign indicates the direction of y-axis

Answer 2

The effect produced by the electric current existing on the rod would be with a -ve sign.

Find the reference direction

To find the rod's electric field, we will determine EMF by considering the ends of the path as 'a' and 'b.'

As we know,

The relation of EMF can be displayed as:

$E = Blv$

Where;

B denotes magnetic field

$l$ denotes the rod's length

v stands for the speed tithe

and,

The negative(-) sign signals the y-axis' direction.
