# FIGURE shows a vertically polarized radio wave of frequency traveling into the page. The maximum electric field strength is . What are a. The maximum magnetic field strength? b. The magnetic field strength and direction at a point where , down?

a) Maximum magnetic field,

b) Magnetic field strength and direction,

See the step by step solution

## Step1: Magnetic field

A region around a magnet or materials that function like magnets in which a force attracts some metals towards it

## Step2: Find Maximum magnetic field

Given Values

The relation between magnetic and electric field in an electromagnetic field is given by:

From the previous relation, we have to find :

(Divide both sides by )

(Substitute the values in equation)

## Step3: Find Magnetic field strength and direction

Given values:

The magnetic field's magnitude is given by,

( Divide both sides by )

(Substitute values in equation)
