which best explains horatios error?\nmagnetism is not produced by electric currents unless the wire is coiled.\nthe magnetic field does not continually spread outward from the wire.\nthe magnetic field is produced inside the wire, not outside of it.\nmagnetism is only produced when a metal bar is placed near the wire.

Answer

Brief Explanations:

  1. Analyze Option 1: A straight current - carrying wire also produces a magnetic field (Oersted's discovery), so the claim that the wire must be coiled is wrong.
  2. Analyze Option 2: The magnetic field around a current - carrying wire is in the form of concentric circles, not spreading outward like radial lines as shown in the diagram. This option correctly identifies the error in the diagram's representation of the magnetic field.
  3. Analyze Option 3: A magnetic field exists both inside and outside a current - carrying wire (with different properties), so this statement is incorrect.
  4. Analyze Option 4: Magnetic fields are produced by the electric current in the wire, not dependent on a nearby metal bar, so this is wrong.

Answer:

The magnetic field does not continually spread outward from the wire.
