False statement regarding inter poles in dc machine is:
1
inter poles are placed along the inter polar axis.
2
inter poles causes demagnetization at the trailing pole tip, magnetization at the leading pole tip
3
inter poles are narrow poles placed exactly midway between the main poles
4
the polarity of the inter poles is the same as that of the main field pole behind in the direction of generator rotation
