How do scientists know that fields exist?

Question

A By detecting noncontact forces near a field's source

B By measuring the mass of fields

c) By touching the fields

D) By observing objects with mass

Answer 1

The correct answer is A) By detecting noncontact forces near a field's source.

Scientists understand that fields exist because they can observe the effects of these fields, such as gravitational, electric, and magnetic fields, on objects without physical contact. For example, the force of gravity can cause objects to accelerate toward each other even when they are not in contact. Similarly, electric and magnetic fields can exert forces on charged particles and magnetic materials, which can be measured and detected.
