A technician compares two regions on a magnetic field-line map for a loudspeaker magnet. In region X, adjacent lines are almost straight and are 4 mm apart. In region Y, adjacent lines curve sharply and are 10 mm apart.
Which statement about the magnetic field in the two regions is correct?
The field is stronger in region Y, because its lines curve more sharply.
The field is stronger in region Y, because its lines are further apart.
The field is stronger in region X, because its lines are closer together.
The field is stronger in region X, because its lines are straighter.
