## anonymous one year ago How strong is a Tesla and how strong is a Newton?

1. anonymous

a Tesla is a very large unit of magnetic field, for example I remember there were some strong electromagnets in some place (I don't remember) that had a magnetic field in the order of 1 Tesla, the field was so strong that people were to make sure not to bring any metallic or any such thing that would be attracted by a magnetic because the field would be so strong people would be pulled along with the metal, if it's not already ripped off from their clothes. A newton is however not as big of a unit as tesla, for example the weight of a medium sized apple is about a newton

Even the magnetic field of earth is on the order of microtesla $|\vec B_{earth}|\approx25 \mu T-65 \mu T=0.25G-0.65G$ Here, G is gauss, another unit for magnetic field $1G=10^{-4}T$

He is right.

Awesome this was the kind of answer I was looking for, thanks.
