Question 1

When do I use millitesla vs tesla?

Accepted Answer

Tesla for strong fields (MRI: 1.5-7 T, superconducting magnets). Millitesla for moderate fields (permanent magnets: 100-400 mT). Microtesla for weak fields (Earth, biomagnetism).

Question 2

How strong is 1 millitesla?

Accepted Answer

1 mT = 10 gauss = 1000 μT. A strong permanent magnet is 100-500 mT at surface. A neodymium magnet can reach 1.4 T (1400 mT). Earths field is only 0.025-0.065 mT.

Question 3

What's a typical magnetic field strength?

Accepted Answer

Earth's field: 25-65 microtesla. Fridge magnet: 5 millitesla. MRI machine: 1.5-3 tesla. Strongest lab magnets: 45+ tesla.

Question 4

Why do we have both Tesla and Gauss?

Accepted Answer

Tesla is the SI unit; Gauss is the older CGS unit. 1 Tesla = 10,000 Gauss. Both remain in use across different fields and regions.
