NOTES ON THE THEORY OF ELECTRONS 11 



rest of the atom ; and the magnetic effect of the negative electron 

 will greatly exceed that of the positive. 



Of course the above idea as to the origin of the pressures and 

 tensions in an electric field is applicable also to the magnetic field, 

 the tension being due to the mutual attraction of the elementary 

 magnets or revolving electrons along the line of the magnetic 

 polarization, and the pressures to the mutual repulsions perpendic- 

 ular to this line.
