Amagnetic field would be produced by a beam of(1)x rays(2)gamma rays(3)protons(4)neutrons

(3) protons

Explanation:

Magnetic fields are produced by charged particles in motion. Let's analyze each option:

(1) x rays --> they consist of photons, which are neutral particles, so they don't produce magnetic fields

(2) gamma rays --> they consist of photons, which are neutral particles, so they don't produce magnetic fields

(3) protons --> protons are charged particles, so they can produce magnetic fields if they are in motion

(4) neutrons --> neutrons are neutral particles, so they don't produce magnetic fields

i believe the answer is:   psychological  experiment

in this experiment, wilhelm wundt became the first person that implement scientific method in analyzing the pyschological phenomenon.

due to this result, wilhelm wundt also able to make psychology to be acknowledged as a separate scientific field from biology.

add the answer choices and i'll give you the answer
