Physical science is defined as the study of observable phenomena in the universe.<span>The main idea of physical science is known as the "scientific method". </span>
<span>This method states: </span>
<span>1. observe a "real" ( not imaginary ) phenomena. </span>
<span>2. make a hypothesis ( or theory / idea ) that EXPLAINS this phenomena. </span>
<span>3. conduct a real experiment to test this hypothesis. </span>
<span>4. confirm that the experiment validates the original hypothesis and if necessary amend the theory. </span>
<span>This method is responsible for virtually every scientific explanation of every kind. </span><span>It has worked so well that the very communication you are having with me is a result of the wonders of physical science. </span>
<span>Hope your question was answered :)</span>
Answer:
the magnetic field is leaving the sheet
Explanation:
The magnetic force is given by the expression
F = q v x B
where bold letters indicate vectors, the modulus of this expression is
F = q v B sin θ
the direction of the force is given by the right hand rule, for a positive charge
the thumb indicates the direction of the speed, in this case from right to left
the palm the direction of the force, in our case upwards
the fingers extended the direction of the magnetic field, this case after fixing the other two components it points out of the blade
In short the magnetic field is leaving the sheet
