Identify whether the following statement is true or false. Some magnets only have a north pole but no south pole.

Magnetic declination is the difference between magnetic north and true north.Question 22Answera.Trueb.False

Which of the following statements about permanent magnets is incorrect?They produce their own magnetic fields and always have a north pole and a south poleThe force between two permanent magnets will increase when they are brought closer to one anotherThey can be attracted to or repelled by other permanent magnetsUnder certain circumstances, they will only be attracted to other permanent magnets5An iron nail is initially unmagnetised.  Which one of the following things will occur when it is brought closer to the north pole of a permanent bar magnet?Nothing will happen since the iron nail is not a permanent magnetThe iron nail will be repelled by the bar magnetThe iron nail will be permanently magnetisedThe end of the nail which is placed closest to the north pole of the bar magnet will become an induced south pole

From those listed, which of the statement about the dip of a magnet is TRUE?Select the correct response:At the magnetic equator, the dip is zero and the directive force greatestAt the magnetic poles, the dip is least and the directive force is reducedAt the magnetic poles , the dip is least and the directive force is the greatestAt the magnetic equator, the dip is maximum and the directive force the least

Read the following statements and choose the correct option.I. The magnetic field at north pole of a bar magnet is greater than the magnetic field at the south pole of it.II. The magnetic field at south pole of a bar magnet is greater than the magnetic field at North pole of it.III. Inside the bar magnet, magnetic field lines run from its south pole to north pole.A Only I is correct B Only III is correct C Both II and III are correct D Both I and II are correct
