A cardiac pacemaker can be affected by a static magnetic field as small as 1.7 mT. How close can a pacemaker wearer come to a long, straight wire carrying 17 A

Explanation:

Given data

B=1.7 mT

I=17A

To find

How close can a pacemaker wearer come to a long r=?

Solution

Use the equation B=(μ₀I)/2πr but instead of calculation B we will rearrange the equation to find r

So

B=(μ₀I)/2πr

r=(μ₀I)/2πB

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.
