# An example of magnetohydrodynamics (MHD) comes from the flow of a river (salty water). This fluid interacts with the Earth’s magnetic field to produce a potential difference between the two river banks. How would you go about calculating the potential difference?

The potential difference can be calculated by determining the velocity difference.

See the step by step solution

## Step 1: Definition of magnetohydrodynamics (MHD)

The study of the magnetic characteristics and behavior of electrically conducting fluids is known as magnetohydrodynamics. Plasmas, liquid metals, salt water, and electrolytes are examples of magneto fluids.

## Step 2: Explanation of calculating the potential difference

By calculating the velocity difference on both sides of the bank. The induced voltage difference is proportional to the velocity difference.
