I need help with these multiple choice questions!

Question 3 [1 point] E-ll Magnetic fields are strongest O A} near the equator. O 3} near the poles of a permanent magnet. 0 Cl near copper bars that have received a static negative charge. 0 '3'} near concentrations of positive charges- Question 4 [1 point] EIn A magnetic field map shows 0 A} relative strength of the magnetic field. 0 B} the direction of the magnetic field. 0 C} All of these choices are correct. 0 D} a few representational field lines. Question 1 [1 point] For a bar magnet, the magnetic field lines point 0 A} always towards the magnet. O 3} always away from the magnet. O C] towards the South pole. O '3'} towards the North pole. Question 2 [1 point] Elma Magnetic field lines 0 A] are straight lines. 0 3} form continuous loops. 0 C] None of these choices is correct. 0 D} are always circles. Question 5 [1 point) =n Magnetic field lines 0 Al can cross each other when the field is strong. 0 Bl are yisihle lines seen around magnets. 0 Cl indicate which way a compass needle would point if placed near the magnet. O D} can easily be drawn within the subatomic structure of a magnetic atom. Question 6 [1 point) EII: What happens to the direction of the magnetic field lines when the magnet responsible for them is reyersed? 0 Al The direction of the magnetic eld lines is reyersed. 0 Bl The direction of the magnetic field lines stays the same. 0 Cl None of these choices is correct. 0 D} The field density increases. Question 7' [1 point] EI: According to the law of magnetic poles 0 Al a magnetic South pole would attract a magnetic South pole. 0 Bl magnetic poles in a bar magnet cancel each other out. 0 Cl a magnetic North pole would repel a magnetic South pole. O D} a magnetic South pole would attract a magnetic North pole
