Question

which of the following is true about the relationship between electricity and magnetism? electricity can be used to create a magnet magnetism and electricity cannot be converted into one another magnetism is based on how gravity attracts electrical energy electrical energy and magnetism cancel each other out question 31 1 pts what will happen if you increase the electric current that is flowing through an electromagnet? the magnet will become weaker the poles of the magnet will reverse the magnet will become stronger the magnet will become permanent

Explanation:

• For the first question:
• Electricity can be used to create a magnet (electromagnet). A current - carrying wire produces a magnetic field.
• Magnetism and electricity can be converted into one another (e.g., electromagnetic induction and electromagnets).
• Magnetism is not based on gravity attracting electrical energy. Magnetism is a separate fundamental force related to moving charges.
• Electrical energy and magnetism do not cancel each other out; they are interrelated (e.g., in electromagnetic waves).
• For the second question:
• The strength of an electromagnet is given by \(B=\mu_0nI\) (where \(n\) is the number of turns per unit length and \(I\) is the current). As \(I\) (current) increases, the magnetic field \(B\) (strength of the electromagnet) increases.
• Increasing the current does not make the magnet weaker. Reversing the current (not increasing it) reverses the poles. And an electromagnet is not made permanent by increasing the current.

Answer:

• First question: Electricity can be used to create a magnet.
• Second question: The magnet will become stronger.
