In an electrostatic field, positive charges (red terminal) are attracted to negative charges (blue terminal), while in a magnetic field, they are attracted to the ______ pole, respectively. Electrostatic induction is associated with the charging of a charged body on an uncharged one and the determination of opposite signs on it. Magnetic induction is associated with the attraction of the needle and the determination of the magnet. B. In an electrostatic field, electric charges are monopoles, and in a magnetic field ______.
