2/12 and 3/8 Hope it's right YAYYYYY
U can do this 2 ways...
26.50 + 0.06(26.50) = 26.50 + 1.59 = 28.09 <==
or
1.06(26.50) = 28.09 <=
I need to se the blanket to answer
It can increase the field because of the loops around the electromagnet like a conductor which can amplify the magnetic field making it go further
