1. If a DC source only is connected to the primary of a linear transformer such as to produce flux linking the primary and secondary coils there will be a steady state voltage generated in the secondary coil.

2. In the case of a linear transformer the reluctance of the core magnetic material would appear the same if measured from either the primary or secondary windings

3. In most transformer cores the reluctance of the airgaps is negligible when compared with the reluctance of the core material

4. Aluminum is frequently used in transformer cores because it is mechanically light, strong and is characterized by a very high relative permeability BCr>>1.

5. For most low reluctance materials currently available and used in practical magnetic devices such as transformers, the slope of the BH curve may be always be considered constant over the possible range of operation of the device.
