The magnetic holder 200 may have S polar small-sized and weak-magnetic magnets 200b adjacent to each of the N polar big-sized and strong-magnetic magnets 200a.

[0102] In this way, between each S polar thin-filmed magnet 401 of a magnetic attachment 40 as described below with reference to FIG. 7 and each of the N polar big-sized and strong-magnetic magnets 200a, an attraction force may occur. Between each S polar small-sized and weak-magnetic magnet 200b and each S polar thin-filmed magnet 401 of a magnetic attachment 40 as described below with reference to FIG. 7, a weak repulsion force may occur. The weak repulsion force may allow accurate positioning between the holder 200 and the magnetic attachment 40.

[0103] The polarity setting between the holder 200 and the magnetic attachment 40 may be only an example. A number of the magnets may be only an example. Thus, the present disclosure is not limited to the above example.

[0104] FIG. 7 is an exploded view of a magnetic attachment for a mobile device in the set for holding and charging the mobile device in accordance with one embodiment. The magnetic attachment 40 may have an attachment film 400 to be attached to the mobile device.

[0105] Moreover, the attachment film 400 may detachably be attached to the mobile device at a rear face thereof. The attachment film 400 may be attached to the mobile device using an acrylic tape due to its good water-proof, heat-resistance, and bonding strength, etc.

[0106] Thus, when not charging the mobile device, the attachment film 400 may be detached from the mobile device at a rear face thereof. This may suppress the deterioration of charging efficiency.

[0107] The attachment film 400 may have holes 400a defined therein at predetermined positions thereof. Each thin-filmed magnet 401 may be received in each of the holes 400a. This may allow accurate positioning of the thin-filmed magnets 401, and a surface smoothness of the magnetic attachment.

[0108] In order to minimize a thickness of the magnetic attachment, the thin-filmed magnet 401 may have a thickness of 1 mm or less. The magnetic attachment 40 may be positioned relative to the magnetic holder 200 during attachment therebetween.

[0109] Moreover, the magnetic attachment 40 may have a contact pad 402 to be attached to the anti-slippery pad 207.

[0110] Each of the contact pad 402 and anti-slippery pad 207 may be made of a synthetic resin or rubber. This may ensure reliable attachment between the contact pad 402 and anti-slippery pad 207.

[0111] Moreover, each of the contact pad 402 and anti-slippery pad 207 may have a specific color. This may impose a specific design and appearance thereof.

[0112] Thus, the magnetic attachment 40 may be formed of a combination of the attachment film 400, the thin-filmed magnets 401 and the contact pad 402.

[0113] In another embodiment, the magnetic attachment may be disposed not out of the mobile device but therein. In this connection, a thin-filmed guide sticker may be attached onto the outer face of the mobile device to indicate a position of the magnetic attachment.

[0114] FIG. 8 is a perspective view of a set for holding and charging a mobile device in accordance with one embodiment. The magnetic attachment 40 on the rear face of the mobile device may be magnetically coupled to the holding and charging sub-assembly 20.

[0115] FIG. 9 is a top view of a charging receiver disposed in the mobile device in accordance with one embodiment. The charging receiver 50 may have the secondary coil 50a embedded therein. The charging receiver 50 may have the male terminal 50b electrically coupled to the female terminal 60 of the mobile device. Thus, the induction current from the secondary coil 50a may flow via the male terminal 50b to the female terminal 60.
