1.Electric charges that are different (1 point) attract each other. repel each other. exist in pairs. do not interact.
2. Magnetic field lines around a bar magnet (1 point) are only perpendicular to the magnet. spread out from one pole and curve around to the other. cross back and forth over one another. are perfectly straight.
And you think the answers are?
it's the first one, attract each other
1. The electric charges that are different from each other attract each other. This means that if one charge has a positive value and the other has a negative value, they will be attracted to each other. This phenomenon is known as electrostatic attraction. To understand why this is the case, we can look at Coulomb's Law, which states that the force between two charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them. The charges with opposite signs have a product that is negative, resulting in an attractive force.
2. The magnetic field lines around a bar magnet spread out from one pole and curve around to the other pole. This means that the magnetic field lines are not only perpendicular to the magnet but also loop around it. This is due to the magnetic field being induced by the alignment of magnetic domains within the bar magnet. The magnetic field lines represent the direction of the magnetic field at each point. By observing the pattern of these field lines, we can understand the magnetic field's behavior. In the case of a bar magnet, the field lines spread out from one pole (north) and curve around to the other pole (south), forming a continuous loop. This looping pattern indicates the flow of the magnetic field.
