Answer
Having MORE coils in the wire
Explanation
## Step1: Understand the components that impact an electromagnet's strength.## Step2: Recognize that having more coils in the wire increases the total length of wire carrying the current, which increases the electromagnetic field created around the wire.## Step3: Acknowledge that a wooden core would not enhance the electromagnetic effect, as wood does not conduct magnetic fields effectively. Ferromagnetic materials, such as iron, are preferred.## Step4: Identify that decreasing the current would result in a weaker magnetic field being generated because the strength of the magnetic field is directly proportional to the current flowing through the wire.###
## Step5: Conclude that of the options provided, having more coils is the only factor that will actually make an electromagnet stronger.
