Answer 1

The magnetic field strength of the pacemaker wire is 0.2 milliteslas.

Step-by-step explanation:

In order to determine the magnetic field strength, we can use Faraday's Law of Electromagnetic Induction. The formula for Faraday's Law is:

V = B*l*v

Where:

• V is the induced voltage (20.0 mV)
• B is the magnetic field strength (unknown)
• l is the length of the wire (10.0 cm)
• v is the velocity of the wire (10.0 cm/s)

Substituting the given values into the formula, we get:

20.0 mV = B*10.0 cm*10.0 cm/s

Simplifying and converting units, we find:

B = 0.2 mT

Therefore, the magnetic field strength is 0.2 milliteslas.
